Damp proofing London & Home Counties

What is damp proofing?

Damp proofing is a protective process to prevent moisture transmitting into walls that are in contact with the ground. There are two main reasons why damp proofing maybe necessary, one is if a property has damp rising from the ground (rising damp), the other, if it has damp penetrating through the wall laterally, from below the ground (penetrating damp). The two should never be confused, because the only thing they have in common is, they have both originated from damp below the ground.

Rising damp, which is the most common of the two, is the slow transmission of moisture, that rises up the interconnecting pores of the wall by capillary action, whereas penetrating damp is rapidly forced through the wall by hydrostatic pressure. Both can cause considerable damage inside your property and both need different methods of treatment.

Lateral Damp Penetration is when damp penetrates through a wall, from a higher external ground or floor level. It can cause walls to be very wet and often does far more internal damage than Rising Damp.
